Haim's numerous collaborations with fellow teen idol Corey Feldman, including The Lost Boys, License to Drive and Dream a Little Dream earned the pair the nickname "The Two Coreys." They starred in the television reality show The Two Coreys, which aired on A&E for two seasons in 2007 and 2008. On the show, Feldman settled into domestic life while Haim continued his struggles. Both appeared in Lost Boys: The Tribe which was released in 2008.

"I was awakened at 8:30 this morning by my brother and sister knocking on my bedroom door. They informed me of the loss of my brother Corey Haim. My eyes weren't even open all the way when the tears started streaming down my face," Feldman said in a statement. "I am so sorry for Corey, his mother Judy, his family, my family, all of our fans, and of course my son who I will have to find a way to explain this to when he gets home from school. This is a tragic loss of a wonderful, beautiful, tormented soul, who will always be my brother, family, and best friend. We must all take this as a lesson in how we treat the people we share this world with while they are still here to make a difference. Please respect our families as we struggle and grieve through this difficult time. I hope the art Corey has left behind will be remembered as the passion of that for which he truly lived."

"I started on the downers which were a hell of a lot better than the uppers because I was a nervous wreck," he told the paper. "But one led to two, two led to four, four led to eight, until at the end it was about 85 a day. ... The doctors could not believe I was taking that much. And that was just the Valium. I'm not talking about the other pills I went through."

The Canadian-born Haim made his first feature film appearance was in 1984 in Firstborn, but his major break came in 1986 with his starring role in Lucasalongside Kerri Green, Charlie Sheen, and Winona Ryder. Following the film's success, Haim starred in the 1987 television series Roomies.
